    Default Sencha Touch 2.1 List twitches

    Hi, everyone!
    Has anybody solved the problem in ST 2.1 on iOS (or even on Android) pointed in subj? After upgrading to version 2.1 I noticed that on iOS list twitches/flickers during the scrolling. Even on small data. It's really noticeable and annoying. For instance, check out Kitchen Sink for 2.0.1 and 2.1:
    ST 2.1

    ST 2.0.1

    I don't notice any issues with the list on the iPad 2. I'm not sure if it is device related though.

    I asked two of my colleages test it on iPod (4th Gen) and both pointed that list in ST 2.0.1 is obviously smoother.

    I thought that it's only our problem. But according the following post of user olegtaranenko it isn't so:

    Default We have the same problems

    The twitches are so noticeable it feels like a major performance degrade. I think this happened after their re-implementation for the list in order to handle large lists by recycling the dom elements. The little twitch happens exactly when a dom element leaves the screen. Hopefully this can be taken seriously as prioritized issue!

    We're seeing the same thing here. Is there any way to turn off that functionality?
